WWE's biggest competition is about to get even more competitive. TNA wrestling bosses met with Spike TV executives Wednesday to discuss moving the group's flagship wrestling show to a primetime weeknight slot.

Although nothing has been announced, it's expected TNA Impact will be moved to 8 p.m. Thursday nights, serving as a lead-in for the new season of the Ultimate Fighter. It currently airs late night Saturday.

It's also possible the show would be extended from 60 to 90 minutes.

This is a huge coup for the upstart grappling group, which has struggled with hefty financial losses over the past three years.

TNA scored its biggest rating to date last weekend, landing a 1.1 -- that's more than a million American viewers -- for the TV debut of Sting.

The number is even more im

pressive considering the show airs in such a late-night spot on a Saturday, traditionally a death night for TV.

TNA's product takes a 'more action, less talk' approach, compared to WWE's skit-heavy episodes. Fighting in a six-sided ring, the group features stars such as Christian, Jeff Jarrett, the Dudley Boys and AJ Styles.

MATCH A SLAM DUNK? Carlito vs. Shaq at Wrestlemania? It doesn't look like it's going to happen, but WWE sure seemed to be planting the seeds for something last weekend.

WWE crews filmed a backstage segment at a Miami Heat basketball game where Carlito started trash talking with Heat player Jason Williams, only to be whacked with a steel chair by Shaquille O'Neal.

BLISS COMEBACK: Although Christy Hemme's team didn't make the Lingerie Bowl finals, the former WWE diva will still likely appear on the Super Bowl half-time pay-per-view tomorrow.

Hemme's team, the Chicago Bliss, lost to the New York Euphoria at a 'Garter and Lace' championship game last Saturday.

Hemme is still expected to appear at tomorrow's game, as she has been heavily pushed as a celebrity quarterback in promotion for the event.

Hemme was released from her WWE contract late last year.

HART IN PILOT: Calgarian Teddy Hart will be among the grapplers taking part in a pilot for an MTV wrestling show.

Set to film in Los Angeles next week, the unnamed show will fuse wrestling and music with elements of reality TV to create a cosmetic, MTV-friendly fight show.

Sean (X-Pac) Waltman, Jack Evans and Justin Credible are also booked for the pilot.
